In current years, so-called `non-conventional’ yeasts have gained considerable interest for several reasons. Initial, S. cerevisiae is really a Crabtree positive yeast that covers most of its ATP requirement from substrate-level phosphorylation and fermentative metabolism. In contrast, a lot of the non-conventional yeasts, such as Yarrowia lipolytica, Kluyveromyces lactis or Pichia pastoris, possess a respiratory metabolism, resulting in substantially higher biomass Correspondence: [email protected] 1 Institute of Molecular Biosciences, BioTechMed Graz, University of Graz, Humboldtstrasse 50II, 8010 Graz, Austria Full list of author details is accessible at the end on the articleyields and no loss of carbon because of ethanol or acetate excretion. Second, S. cerevisiae is extremely specialized and evolutionary optimized for the uptake of glucose, but performs poorly on most other carbon sources. Several nonconventional yeasts, on the other hand, are in a position to develop at higher growth prices on alternative carbon sources, like pentoses, C1 carbon sources or glycerol, which may very well be accessible as low cost feedstock. Third, non-conventional yeasts are extensively exploited for production processes, for which the productivity of S. cerevisiae is rather low. Prominent examples are the use of P. pastoris for highlevel protein expression [2] and oleaginous yeasts for the production of single cell oils [3].

A single such tool may be the use of reconstructed metabolic networks for the computational evaluation and optimization of pathways and production processes. These genomescale Fexinidazole Cancer models (GSM) are becoming increasingly crucial as whole genome sequences and deduced pathways are readily available for a lot of distinct organisms. In mixture with mathematical algorithms like flux balance evaluation (FBA) and variants thereof, GSMs have the prospective to predict and guide metabolic engineering tactics and substantially boost their achievement rates [4]. FBA quantitatively simu.
